At a continuous casting plant steel ingots are cast and then cut to appropriate length. Due to the high temperatures, scale develops on the outside of the ingots and is rinsed away in chutes with water to a basin. The scale takes the form of grains some 5 mm in size and causes serious wear in the chutes. Nowadays it has become a standard throughout the world to line such chutes with ABRESIST fused basalt. The smooth surface reduces any deposition of material during transport, as well as protecting against abrasion wear.

Danieli is a global provider of iron and steel making technology. An important application is the transforming process from iron ore to direct reduced iron (DRI) which is done in the DRI reactor. In the DRI reactor one of the more sensitive parameters for maintaining product quality and performance is the discharge temperature of the pellets used to feed the electric arc furnace (EAF). Likewise, for feeding pellets to the hot briquetted iron (HBI) machine. The higher the temperature, the better will be HBI quality.

The cascade chute is a fail-safe means of conveying materials located at the top of a blast furnace. Raw materials, including heavy hot briquetted iron (HBI), are deposited onto the chute via the transport and conveyance systems to which it is connected. Such materials cause a great deal of abrasion and impact wear.

Handling Abrasive Sludge Materials with Wear Resistant Pipe Linings

KALCRET ANX is a low-cost version of the trowel-application hard compounds for protecting plant components and piping systems against wear. KALCRET ANX offers remarkable resistance to wear at operating temperatures of up to 400°C with exceptional value for money. The basis for the cement-bonded material KALCRET ANX is supplied by selected hard materials of high quality, such as basalt.

Coal is one common raw material for the manufacture of coke, which is used as the fuel for blast furnaces. One leading steel producer in India therefore runs its own coal mines in the country. These sites have their coal washeries which employ “dense media” cyclonic separators.

At its factory in Ghent, one of the largest steel producers in the world makes steel products for a wide variety of applications, e.g. in the automotive and building industries. The plant has two blast furnaces, which are continuously filled with coke, sinter and pellets. The result is production of 4.8 million tonnes of pig iron every year.

Vibrating conveyors are a type of conveyance system which uses vibration to convey materials along a horizontal route. In steelworks, for example, they are used underneath ore bunkers for the discharging of sinter materials. Such material causes major wear to the conveyors, frequently resulting in abrasion damage to the system. The lifetime of such vibrating conveyors can be considerably extended by means of effective wear protection.

About 30% of the steel manufactured in Germany is made of recycled scrap metal. The old scrap material is not rendered molten in a blast furnace but in an electric arc furnace with the help of a DC arc process. This process requires an electric arc with 100 megawatts of power which is ignited in the furnace to produce temperatures of about 1,600°C. The flue gas, which is developed as the metal melts, flows out through a modern flue gas cleaning plant before being vented from the works.
